CHARLES W. CARTER, OF \VESTVILLE, INDIANA, ASSIGNOR TO LESTER L. BOND AND GEORGE COATSXVORTH, OF CHICAGO, ILLINOIS.

CORN-SHELLER.

Specification of Letters Patent No. 23,424, dated March 29, 1859.

To all whom it may concern:

Be it known that I, CHARLES 7. CARTER, of the town of Vestville, in the county of Laporte and State of Indiana, have invented a new and useful Machine for Shelling Corn, called a Corn-Sheller, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a front elevation o f the same showing the crank cog wheels, &c.; Fig. 2 a side elevation with part of the external truncated cone removed so as to exhibit the internal sectional cone and Fig. 3 a part of the upright shaft and onefourth part of the internal cone which is separated from the shaft at the top to show the manner of its connection and joined at the bottom showing the movable pintle and guide spring.

In the drawings A represents the frame of the machine, B hopper fastened to the top of frame, C plate or bar across the hopper in which the head of shaft revolves, E center on across bar of frame at which the foot of the shaft revolves, D upright shaft, G cog wheel by which the shaft D is made to revolve, H horizontal shaft with mitered cog wheel, I cog wheel by which the shaft H is made to revolve, K cog wheel on crank shaft, L crank, M mitered cog wheel by Ywhich the external cone is made to revolve, N plate or bar across the bottom of external cone attached to the wheel M and by which the cone is held in place, O external truncated cone, P internal sectional cone, Q circular plate on the top of shaft D in which the sections of cone P are fastened, R pins inserted in plate Q, S pintle, T holes through .which the pintle S plays, U spring, V triangular spiral ridges on the external surface of the cone P, 7 similar ridges on internal surface of cone O, o a belt wheel on crank shaft, b Z) fly wheel on shaft H.

The nature of my invention consists in construct-ing' a machine with two cones revolving in opposite directions, the internal cone P accommodating itself to the size of the ears of corn passing through by being made in sections, which sections are hinged at the top by the hinge R- or any equivalent device, held in place at the bottom by the pintle S, and made to operate against the external cone O by means of a guide spring U, forming a complete machine in combination with the other parts shown and described herein.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

I construct my machine entirely of iron although the frame by using a different form may be made of wood of any desired size or height. The cones O and P are about one and onehalf feet in length and of any required diameter. The external cone O is made hollow with triangular ridges on the inner surface. The internal cone P is made in sections of which four is the number found best in working. The sections or quarters are hinged at the top in the plate()J and are held in place at the bottom laterally by the pintle S which slides in the holes T through the shaft D and are held in place centrifugally by the guide spring U which also regulates the space between the cones and adapts it to the size of the ears of corn passing through. The external surface of the cone P and the internal surface of the external cone O have triangular ridges or rows of teeth upon them about four inches apart and running spirally in opposite directions.

The power is applied at the crank L or belt wheel al a and is communicated to the cog wheel K, from that to the cog wheel I on the shaft H with mitered cog wheel by which the mitered cog wheels M and G are made to revolve (these wheels may be either mitered or plain). The wheels M and G revolve in opposite directions which produces a rapid motion without great loss of power. The cog wheel G is attached to the shaft D. The cog wheel M is held in place by a pin through the shaft D immediately below it and supported by a washer. It is attached firmly to the plate or bar N both of which revolve around the shaft D and the plate or bar N supports the cone O. The corn after passing through the Sheller may be separated from the cobs by placing any Ordinary Separator under the machine.

What I claim as my invention and desire j to secure by Letters Patent is:

The sectional truncated cone P oonstruoted as described With the pint-1e S, guide spring U, and hinge R and arranged to 0perate in combination with the outer cone O in the manner and for the purposes speoied. lu
